Patent CA-2270833-C (CA)
Inventor: ZAMFES KOSTA
IPC: G01N1/22

Abstract: A gas trap liberates subterranean gases entrained in drilling muds. The trap introduces a stripping gas into a flow of mud gas for liberating mud gases. The trap comprises a pair of opposing truncated right circular vessels and having a concentric bottom mud inlet, a side mud outlet and a gas collection port in the freeboard area at the top. A stirrer depends vertically into the trap. The stirrer has radial tubes extending from its lower end and inlet ports at its top end for forming a continuous bore and flow passage therethrough. The radial tube ends are bevelled on the trailing edge. The trap is partially immersed in mud forming a mud level in the trap and a freeboard area above containing air. When rotated, the hollow shaft spins the mud, establishing a flow through the trap and forming a turbulent low pressure area at the bevels, drawing air down the shaft from the upper ports and injecting stripping air into the mud, all of which aids in liberating gases from the mud.

Abstract: An adjustable register includes a frame member having an air passage therethrough, a plurality of slats connected pivotally to the frame member, a slat connecting member connected to each of the slats, a slat-controlling linkage connected pivotally to one of the slats, a toggle-joint mechanism connected pivotally to the slat-controlling linkage on the frame member, and a plurality of blocking bars on the frame member.      As the toggle-joint mechanism is operated, the slat-controlling linkage is driven to drive one of the slats. All slats move concurrently between a closed position where the slats contact closely the blocking bars, and an open position where the slats allow air flow through the air passage. In the closed position, the air-tight effect of the register is ensured.

Abstract: Un étudiant utilisateur d'un ordinateur client fait appel à un processus d'apprentissage pour développer ses aptitudes cognitives et un superviseur utilise un second ordinateur client pour surveiller à distance les progrès de l'étudiant. Le processus d'apprentissage présente différents types de stimuli à l'étudiant et enregistre les réponses de l'étudiant associées aux stimuli. En outre, le processus d'apprentissage forme des données d'évaluation à partir des réponses de l'étudiant, lesdites données d'évaluation représentant une corrélation entre les réponses de l'étudiant associées aux stimuli respectifs et des données de réponses correctes préétablies associées aux stimuli respectifs. En outre, le processus d'apprentissage modifie son propre comportement en fonction des données d'évaluation de manière à personnaliser le comportement du processus d'apprentissage aux aptitudes cognitives de l'étudiant. Les réponses de l'étudiant sont téléchargées dans une base de données globale des étudiants à laquelle peut accéder un superviseur. Le superviseur interroge cette base de données globale pour en extraire des réponses de l'étudiant qu'il analyse. Le superviseur peut utiliser ultérieurement cette analyse aux fins d'une consultation directe avec l'étudiant ou peut conseiller des changements de comportement du processus d'apprentissage dans le but de développer plus efficacement les aptitudes cognitives de l'étudiant.

Abstract: A method for configuring a digital overcurrent relay to provide a plurality of selectable time overcurrent characteristic responses corresponding to a plurality of target curves. According to one embodiment, a template curve is selected from the plurality of target curves, and a scaling factor is generated for each remaining target curve, wherein the relay comprises means for generating approximated curves from a given template curve and a given scaling factor. It is determined whether each approximated curve is within a threshold amount of total error with respect to its corresponding target curve. If any approximated curves are above the threshold amount, then a further template is selected from the plurality of target curves, and scaling factors are again generated and adjusted for the further template curve, until no approximated curves are above the threshold amount.

Abstract: The state of polarization of an input light beam is tested by determining four components of a Stokes vector of the light. These correspond to components of the light in three polarization states, S1: linear horizontal, S2: linear at 45 degrees, S3:  right circularly polarized, and S0 the total power. It is not necessary to filter out these components directly and measure their powers. In accordance with this invention it is more convenient to measure the powers in three arbitrary polarization states that have known relationships to each other, and, also measure the total power. The actual Stokes vector components is calculated from this information. Conveniently, a device having three polarization beam splitting surfaces and a prism provides a novel way in which to obtain the necessary information from an input beam so that a set of equations can be solved to determine the state of polarization the input beam.

Abstract: An automatic compliance testing system for desktop designed consumer packaging. The automatic compliance testing system comprises an Encapsulated PostScript TM barcode file which includes an executable self-checking module which tests the barcode file for specification violations to the UPC barcode definition. The results of the self-checking operation are communicated to a checklist module. The checklist module is an executable module which generates a checklist that displays the test results. The checklist may be placed at any location, scaled, mirrored or rotated within the design document but in most cases adjacent to or outside the boundaries of the consumer packaging being designed. The automatic compliance testing system provides the capability for a PostScript TM imaging device or PostScript TM RIP software package to check compliance of the defined barcode with predetermined specifications and to indicate problems with the barcode which would result in a failed Certificate of Conformity and/or attendant non-compliance penalties.

Inventor: KINDBEITER FRANCIS
IPC: F25B49/04

Granted: 2008-01-08
Abstract: The invention concerns a method for controlling a thermochemical reaction or a solid-gas adsorption being carried out in a reactor (10) containing an active agent capable of reversibly reacting with a gas, the reactor (10) being connected to an evaporator/condenser assembly (14) for the gas by a connection (12) without control valve, the reactor (10) and the evaporator/condenser assembly (14) each provided with means for selectively exchanging calories with their surroundings. The control method consists in: thermally insulating the reactor (10) and the evaporator/condenser assembly (14) from the surroundings; thermally communicating the reactor (10) with its surroundings so that the active agent reacts with the gas, thereby providing cold to the evaporator (14); thermally communicating the evaporator (14) with its surroundings so as to cool it selectively; and selectively insulating the reactor (10) or the evaporator/condenser assembly (14) from their surroundings so as to stop the reaction at one point of the reversible cycle.

Title: Pile a combustible a electrolyte conducteur protonique
Inventor: DOHLE HENDRIK
IPC: H01M8/1053
Filed: 1999-01-14
Granted: 2008-06-10
Abstract: Les piles à combustible de type connu à électrolyte conducteur protonique utilisent comme électrolyte une membrane en matière plastique perfluorée et fonctionnent à l'hydrogène ou au méthanol comme combustible. L'inconvénient de telles piles est que cette membrane électrolyte laisse passer non seulement les protons mais également le combustible, ce qui abaisse le rendement de la pile. La migration des molécules de combustible de l'anode vers la cathode à travers l'électrolyte (14) est empêchée grâce à l'invention, laquelle est caractérisée en ce que la pile à combustible présente un composite à couche d'arrêt (20) perméable à l'hydrogène, comprenant deux couches externes (22, 24) et une couche centrale (26) disposée entre celles-ci, en ce que chaque couche externe est en palladium et/ou en alliage de palladium, et en ce que la couche centrale est en niobium et/ou en tantale et/ou en un alliage à base de l'un de ces métaux. Le palladium, le niobium et le tantale présentent un haut pouvoir de diffusion pour l'hydrogène atomique, tout en étant imperméables à de plus gros atomes et molécules. Le composite à couche d'arrêt sépare le volume gazeux anodique du volume gazeux cathodique, de telle façon que le combustible ne puisse migrer à travers l'électrolyte vers la cathode.
